[0030] The preparation method of the novel insulating brick comprises the following steps:

[0031] S1: Preparation of hollow bricks

[0032] Mix cement, shale ore, ceramsite, lime, and pumice, and stir evenly at a speed of 200-400r / min to make hollow bricks;

[0033] S2: Preparation of foamed material

[0034] S21: Stir cement, glyoxal and water evenly at a speed of 100-300r / min to prepare a slurry;

[0035] S22: Calcium carbonate, barium sulfate, bentonite, magnesium borate, rice straw powder, AR glass fiber, carboxymethyl cellulose, water reducer, foaming agent, foam regulator, catalyst, crosslinking agent and stabilizer The foaming agent is stirred for 2-3 hours at a speed of 60-100r / min to obtain a foam liquid;

[0036] S23: Add the foam liquid prepared in step S22 to the slurry prepared in step S21, and stir evenly at a rotating speed of 150-200r / min to obtain a foaming material;

[0037] S3: Preparation of insulation bricks

Abstract

The invention discloses a foam material. The foam material is prepared from, by weight, 28-45 parts of cement, 3-4 parts of calcium carbonate, 2-3 parts of barium sulfate, 2-3 parts of bentonite, 1-2 parts of magnesium borate, 1-2 parts of rice straw powder, 0.6-1 part of AR glass fibers, 0.4-0.8 part of carboxymethylcellulose, 1.5-2.5 parts of a water reducing agent, 0.2-0.8 part of a foaming agent, 0.2-0.6 part of a foaming regulator, 0.1-0.3 part of a catalyst, 0.3-0.6 part of a crosslinking agent, 0.1-0.5 part of foam stabilizer, 20-30 parts of glyoxal and 240-300 parts of water. An environment-friendly concrete brick made of the foam material has the advantages of being good in heat preservation and heat insulation performance and sound insulation effect, light, resistant to pressure and the like.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a foaming material. Background technique [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. Existing thermal insulation composite bricks or blocks mainly include multiple forms such as inlaying thermal insulation materials, setting thermal insulation interlayers, thermal insulation holes, and trenches. As one of the thermal insulation materials for houses, non-fired foamed bricks at room temperature are more and more popular because of their thermal insulation, sound insulation, fire prevention, and strength superior to traditional thermal insulation materials. However, the foaming materials currently on the market have disadvantages such as poor impact resistance and rela...
